N2 - Patterns of multiple steady states, due to substrate-inhibition kinetics, are analyzed for a realistic activated-sludge model that accounts for reactor-settler interaction and for the deterioration of settler performance with increased recycle ratio. It is shown that solutions can form, then, isolated branches or mushroom-shaped diagrams rather than the expected hysteresis loop. A systematic methodology for organizing analytical or experimental results, in the form of maps showing domains of bistability, is presented and applied.
